Pure Love in Chinese / Japanese...

純愛 is a Japanese word that means pure love.

純愛 is also a variety of female given names in Japan with these romanizations: Pyua; Hiroe; Sumie; Jun'ai; Ayame; Ayane.

純潔 is associated with "chastity" but with the direct meaning of clean, innocent, and pure.

If you were expressing the idea of a "pure heart" in Chinese, while not literal, this would be the word you would use.

In Japanese, this word is sometimes used to express purity.

In Korean, it describes purity, chastity, virginity, and innocence (basically the same as the Chinese definition).

真実の愛 means "true love" or "genuine affection" in Japanese.

The first two Kanji mean true, real, genuine, or authentic.
The third Kanji is a connecting possessive article.
The last character is love or affection.

真愛 is literally "True Love" in Chinese.

The first character means "real," "true" and "genuine." The second character means "love" and "affection."

During the customization of your calligraphy wall scroll, there is a place to add an inscription. You might want that inscription to be your names in Chinese down the side of your wall scroll, or perhaps just below these two main characters (just $9 extra). A nice gift to celebrate an anniversary or marriage!

我心真愛 is a slightly poetic way to express this sentiment to someone.

The meaning is "My True Love" but the characters directly translate as "I/Me/My Heart/Mind True/Real Love."

Note that Chinese grammar and construction are different, so this sounds very eloquent and artsy in Chinese.
In Korean Hanja, the third character should be written differently, just let me know when you place your order if you want that version - it will still make sense in Chinese. This phrase makes sense in Korean but not commonly used.

純情 means, "Pure Heart" in Chinese, Japanese Kanji, and old Korean Hanja.

It's used to reflect the ideas of being "pure and innocent."

Depending on the context in which this title is used, it can relay "self-sacrificing devotion" or in some cases, "naïveté."
This would be in the same way we might refer to a young girl giving her lunch money to a beggar on the street. She has a pure and precious heart but perhaps is also a bit naive.
